RESULTS:The problem of 637 patients treated with PN included indication,duration,prescription composition and incompatibility. CONCLUSION:The application of PN in our hospital is partly rational,nevertheless there are also some problems needed to be improved.

Thyroid-stimulating hormone receptor(TSHR)is an important autoantigen whose cleavage and shedding can induce autoimmunity.The TSHR is the main functional receptor of the thyroid.The shedding of the ? subunit plays an important role in the forming of TSAb and balancing between TSAb and TBAb.Research on the cleavage and shedding of the TSHR extracellualar domain helps to gain a deep insight into the structure and function of TSHR,illuminate the pathogenesis of autoimmune thyroid disease and find out a new therapy.The structure of TSHR,the mechanism and the significance of its cleavage and shedding are reviewed in this article.

OBJECTIVETo observe the clinical effectiveness of Qilin Pills combined with sertraline in the treatment of secondary non-consolidated kidney qi premature ejaculation (PE).

METHODSA total of 120 patients with secondary non-consolidated kidney qi PE were randomly assigned to groups A (aged [35.5 ± 5.4] yr), B (aged [36.2 ± 5.7] yr), and C (aged [35.2 ± 5.3] yr) in the ratio of 1:1:1 to receive Qilin Pills (once 6 g, bid), sertraline (once 50 mg, qd), and Qilin Pills plus sertraline, respectively, all for 4 weeks. The intravaginal ejaculatory latency time (IELT) and PE diagnostic tool (PEDT) scores were obtained before and after medication and at 1 month after drug withdrawal, and comparative analyses were made among the three groups of patients.

RESULTSThe IELT was dramatically prolonged in groups A, B, and C after treatment ([3.23 ± 1.84], [3.87 ± 2.43], and [5.92 ± 3.11] min) and at 1 month after drug withdrawal ([1.85 ± 1.27], [1.52 ± 1.06], and [ 4.26 ± 1.88 ] min) as compared with the baseline ([0.88 ± 0.45], [0.84 ± 0.47], and [0.85 ± 0.50] min) (P < 0.01), even longer in group C than in A and B (P < 0.01). The PEDT scores of the three groups were 5.1 ± 1.8, 4.9 ± 1.7, and 3.8 ± 1.2 after treatment and 8.2 ± 2.4, 8.1 ± 2.4, and 6.5 ± 2.1 at 1 month after drug withdrawal, significantly improved in comparison with 13.2 ± 3.2, 12.8 ± 3.1, and 13.1 ± 3.4 before treatment (P < 0.01), even more significantly in group C than in A and B (P < 0.01).

CONCLUSIONQilin Pills combined with sertraline has a definite efficacy in the treatment of secondary non-consolidated kidney qi PE and therefore deserves wide clinical application.

Objective To explore the effects of oxidative stress in porcine iliac endothelial cells(PIECs) induced by high glucose. Methods After being intervened by high glucose for some time, dihydroethidium (DHE) or dihydrorhodamine 123 (DHR123) was used as a reactive oxygen species(ROS) capture. The mean fluorescent intensity(MFI) of above probes which were the products of intracellular oxidation was detected by fluorescent microscopy and flow cytometry, and the level of ROS was thus measured. With lucigenin as chemiluminescence agent, luminescence changes were detected by chemiluminescence analyzer after addition of NADPH to observe the effect of high glucose on activity of NADPH oxidase(NOX). Results Intracellular MFI was markedly elevated with the concentration of high glucose and time of exposure to high glucose. It was revealed by flow cytometry that the NOX activity was significantly activated compared with normal medium treated PIECs(P

Objective To investigate the adjustment and value of lymphocyte G protein-coupled receptor kinase-2 (GRK2) protein levels in patients with acute coronary syndrome(ACS). Methods Forty-two patients with stable angina pectoris (SAP), 44 patients with unstable angina pectoris (UAP), 43 patients with acute myocardial infarction (AMI), and 46 patients with normal coronary angiography (NCA) in hospital were enrolled in this study. Lymphocyte GRK2 protein levels were analyzed by Western blot in 24 h after admitted to hospital. Heart rate variability (HRV) analysis was performed based on 24 h Holter electrocardiogram (ECG) monitoring. Cardiac functions were measured using ultrasonic cardiogram. The results were compared and the relationship between GRK2 protein levels and HRV, cardiac functions index was analyzed. Results The level of lymphocyte GRK2 in AMI group, UAP group, SAP group and NCA group was (209.8 ± 63.9)%, (165.6 ± 60.2)%, (131.7 ± 51.8)% and (125.3 ± 50.6)%. The levels of lymphocyte GRK2 in AMI group and UAP group was significantly higher than that in SAP group and NCA group .Moreover, the level of GRK2 was the highest in AMI group, and there were significant differences (P<0.01). The level of lymphocyte GRK2 had negative correlation with high frequency(HF), low frequency(LF), LF/HF, standard deviation NN interval (SDNN), standard deviation of the average normal RR interval for 5-minute segments (SDNNI) and left ventricular ejection fraction (LVEF) (r =-0.52,-0.47,-0.53,-0.56,-0.49,-0.51, P < 0.01). Conclusions The rise of lymphocyte GRK2 protein levels is significantly associated with increased sympathetic nerve excitability and deterioration of cardiac function.

Objective To verify the efficacy and safety of Edaravone,a novel hydroxy-free radical scavenger,on acute cerebral infarction(ACI).Methods We performed a randomized,placebo-controlled,parallel-group,double-blind study on ACI patients. 63 patients,enrolled within 48h of onset,were allocated to Edaravone group( n = 31) or the placebo group( n = 32) randomly. Edaravone was infused at a dose of 30 mg,twice a day,for 14 days. Meanwhile,Hydroxyethylrutin and Aspirin were taken as basic treatment. The therapies of the placebo group were similar to those of Edaravone group except for Edaravone.Before treatment and at 7th,14th and 21th day after treatment,the neurological deficits and activities of daily living (ADL) were evaluated using European Stroke Scale (ESS) and Barthel Index respectively. 3 months later,all the patients were followed up for survival and ADL.Results At 21th day the increase rate of ESS was evaluted.There were significan difference between Edaravone group[(60.3?28.2)%] and the placebo group[( 35.1? 23.6)%]( P

Objective To investigate the correlations between ambulatory arterial stiffness index and intracranial/extracranial arterial stenosis.Methods One hundred and twenty-eight cases of ischemic cerebrovascular disease were collected in our hospital from January 2010 to March 2012.Joint diagnosis of cranial computer tomography(TCD) and magnetic resonance angiography (MRA) and,or CT angiography (CTA) were used to detect the degree and number of intracranial arteries,and in accordance with the lesions level,patients were divided into stenosis group,the mild stenosis group,the moderate stenosis group and severe stenosis group.24 h ambulatory blood pressure was monitored and ambulatory arterial stiffness index (AASI) was calculated and statistically analyzed.Results (1) Age,sex,hypertension proportion of diabetes,body mass index(BMI) of different Intracranial arterial stenosis in four groups did not have significant differences (P ＞0.05),but in AASI the without stenosis group is 0.48 ± 0.15 ; the mild stenosis group 0.62 ± 0.16,the moderate stenosis group 0.61 ± 0.17,severe stenosis group 0.64 ± 0.15,and there was significant difference (F =3.955,P =0.001).(2) Age,sex,hypertension proportion of diabetes,BMI of different extracranial arterial stenosis in four groups did not have significant differences (P ＞ 0.05),but in AASI the without stenosis group was 0.48 ± 0.01 ; the mild stenosis group 0.57 ± 0.11,the moderate stenosis 0.59 ± 0.12,and severe group 0.60 ±0.15,and there was significant difference (F =3.643,P =0.002).In comparison between any two group:light,moderate and severe stenosis AASI were significantly higher than those without stenosis,and there was significant difference (P ＜ 0.05).And there was significant different in AASI among different intracranial and extracranial arterial lesions (F =7.395,P ＜ 0.001).Compared to 0 branch pathological changes,1 branch,2 branch,3 branch and above,there was was significant difference(P ＜ 0.05).Conclusion Based on a 24-hour ambulatory blood pressure monitoring indicators,AASI was mainly reflecting the impact of atherosclerosis on blood pressure,associated with intracranial and extracranial artery stenosis.AASI would play a major role in clinical diagnosis and treatment of ischemic cerebrovascular and forecast.

AIM To explore the effects of trip-tolide on endothelin-1 and its gene expression in lung of asthmatic guinea-pigs. METHODS The contents of ET-1 in lung of asthmatic guinea-pigs were measured with radioimmunoassay, and the expressions of ET-1, ETA, ETB and ECEmRNA with reverse transcription DNA polymerase chain reaction (RT-PCR). RESULTS 0 All of the indexes were increased after guinea-pigs were induced asthma. At the 4th hour after first induction of asthma, ET-1 reached the top, but at the 2rd hour, ET-1mRNA, ETAmRNA and ECEmRNA were markedly higher than control group (P

Objective: To investigate the apoptosis inducing effects of cryptotanshinone (CPT) in human chronic myeloid leukemia K562 cells and its molecular mechanisms. Methods: K562 cells were firstly treated with CPT at different concentration. Then, the inhibitory effect of CPT was detected by MTT assay; morphological changes of cells were observed by inverted microscope; cell apoptosis was detected by Annexin V-FITC/PI staining. Western blotting was carried out to determine the expression of apoptosis-related proteins, including Caspase-3, Caspase-9, PARP, Bax, Bcl-2 and cytochrome C (Cyt C). The mitochondrial membrane potential was measured using JC-1 probe. Finally, the effects of CPT on the proliferation and apoptosis were detected in the absence or presence of inhibitors for mitochondrial permeability transition pore (PTP) and caspase-family. Results: CPT significantly inhibited the proliferation, induced apoptosis and morphological changes of K562 cells. Furthermore, CPT increased the Bax/Bcl-2 ratio obviously, decreased the mitochondrial membrane potential, and enhanced the Cyt C release. CPT also significantly increased the activities of pro-apoptotic proteins, such as Caspase-3, Caspase-9, and PARP. The inhibitors of PTP and caspase-family reduced the pharmacodynamics of CPT obviously. Conclusion: These results show that CPT could significantly induce the apoptosis of human chronic myeloid leukemia cells, in which its function is related with the mitochondrial pathway.
